That's not true for everyone. You're talking about a 28 running on a 32. That's not much of a low gear. I rode across the country in '97 when I was super fit (at the time I did the local training races and I rode sub 5 hour centuries) and that wasn't low enough. I carried reasonably light weight gear and thought that the gearing was not quite low enough.
